    Quiet eye (QE) is the final ocular fixation on the target of an action (e.g., the ball in golf putting). Camerabased eye-tracking studies have consistently found longer QE durations in experts than novices; however, mechanisms underlying QE are not known. To offer a new perspective we examined the feasibility of measuring the QE using electrooculography (EOG) and developed an index to assess ocular activity across time: eye quietness (EQ). Ten expert and ten novice golfers putted 60 balls to a 2.4 m distant hole. Horizontal EOG (2ms resolution) was recorded from two electrodes placed on the outer sides of the eyes. QE duration was measured using a EOG voltage threshold and comprised the sum of the pre-movement and post-movement initiation components. EQ was computed as the standard deviation of the EOG in 0.5 s bins from –4 to +2 s, relative to backswing initiation: lower values indicate less movement of the eyes, hence greater quietness. Finally, we measured club-ball address and swing durations. T-tests showed that total QE did not differ between groups (p = .31); however, experts had marginally shorter pre-movement QE (p = .08) and longer post-movement QE (p < .001) than novices. A group × time ANOVA revealed that experts had less EQ before backswing initiation and greater EQ after backswing initiation (p = .002). QE durations were inversely correlated with EQ from –1.5 to 1 s (rs = –.48 - –.90, ps = .03 - .001). Experts had longer swing durations than novices (p = .01) and, importantly, swing durations correlated positively with post-movement QE (r = .52, p = .02) and negatively with EQ from 0.5 to 1s (r = –.63, p = .003). This study demonstrates the feasibility of measuring ocular activity using EOG and validates EQ as an index of ocular activity. Its findings challenge the dominant perspective on QE and provide new evidence that expert-novice differences in ocular activity may reflect differences in the kinematics of how experts and novices execute skills

    The Adaptation Challenges and Strategies of Adolescent Aboriginal Athletes Competing Off Reserve

    Get PDF
    Within the motivation literature, it has been indicated that athletes respond more effectively to sport’s contextual challenges through effective adaptation skills. Fiske identified five core motives as facilitators of the adaptation process across cultures: belonging, understanding, controlling, self-enhancement, and trusting. Through a cultural sport psychology approach, the adaptation challenges and strategies of Canadian Aboriginal adolescent athletes from one community (Wikwemikong) are described as they traveled off reserve to compete in mainstream sporting events. Concurrently, Fiske’s core motives are considered in relation to youth sport participants from the aforementioned Aboriginal community. Culture sensitive research methods among the Wikwemikong, including community meetings, talking circles (TCs), indigenous coding, and coauthoring, were employed in this article. Data are reflected in three themes: (a) challenges pursuing sport outside of the Aboriginal community in advance of bicultural encounters, (b) challenging bicultural encounters in Canadian mainstream sport contexts, and (c) specific responses to racism and discrimination

    A Qualitative Analysis of Motivation of Elite Female Triathletes

    Get PDF
    The multidimensional theoretical framework of Self-Determination Theory (SDT) has gained prominence in the sport and exercise field to assist in understanding human motivation. While there is extensive research on motivation of recreational athletes, no study has qualitatively examined the motivation of elite female triathletes. The primary purpose of this research was to determine how motivation to train and compete is maintained at the elite level using the Basic Needs Theory. The participants were eight elite female triathletes who competed in International Triathlon Union (ITU) draft-legal Olympic distance, Half- Ironman, and Ironman triathlons. Results from the semi-structured interviews revealed that challenges, love of the sport, and togetherness enhanced motivation to persist in this demanding sport. Several similarities with Deci and Ryan\u27s (2000) Basic Needs Theory were found. Directions for future research using SDT within the sport of triathlon were discussed

    The effects of morning preconditioning protocols on testosterone, cortisol and afternoon sprint cycling performance [conference presentation]

    Get PDF
    Opportunities exist for athletes to undertake morning exercise protocols in an attempt to potentate afternoon performance. Four sub elite track sprint cyclists completed a morning cycling (Cyc) or weights-based protocol (WP) prior to an afternoon cycling time trial (500m) in a repeated measures, counterbalance crossover design. Measured variables included heart rate, blood lactate, cycling peak power, salivary testosterone (T) and cortisol levels along with time trial performance. Standardised differences in means via magnitude-based inferences were calculated using paired samples T-tests in SPSS version 24 with statistical significance set at p < 0.05. The WP produced significantly faster times in the final 250m in comparison to CycP. The anticipated circadian decline of T was observed after the CycP but was however mitigated following the WP. While slight decreases in 500m times were experienced during the WP, they were not significant and were considered within the normal variations experienced between performances by elite athletes. The effect of the WP on the circadian rhythm of T could be linked to a greater recruitment of muscle fibres. Results suggest a morning resistance protocol can positively affect testosterone levels for afternoon performance. Possible gender and individual responses from conducting a W over Cyc protocol were observed and require further investigation

    The purpose of this study was to utilise global-positioning system (GPS) technology to quantify the running demands of national Under 18 field hockey players competing in a regional field hockey tournament. Ten male players (mean ± SD; age 17.2 ± 0.4 years; stature 178.1 ± 5.2 cm; body mass 78.8 ± 8.8 kg) wore GPS units while competing in six matches over seven days at the 2018 New Zealand national under 18 field hockey tournament. GPS enabled the measurement of total distance (TD), low-speed activity (LSA; 0 -14.9 km/hr), and high-speed running (HSR; ≄ 15 km/hr) distances. Differences in running demands (TD, LSA, HSR) between positions were assessed using effect size and percent difference ± 90% confidence intervals. Midfielders covered the most TD and LSA per game and strikers the most HSR during the 6 matches. There were “very large” differences between strikers and midfielders for TD and LSA, strikers and defenders for LSA and HSR, and defenders and midfielders for LSA. These results suggest that these playing positions are sufficiently different to warrant specialised position-specific conditioning training leading into a field hockey tournament

    A department of methodology can coordinate transdisciplinary sport science support

    In the current sporting landscape, it is not uncommon for professional sport teams and organizations to employ multidisciplinary sport science support teams. In these teams and organizations, a “head of performance” may manage a number of sub-discipline specialists with the aim of enhancing athlete performance. Despite the best intentions of multidisciplinary sport science support teams, difficulties associated with integrating sub-disciplines to enhance performance preparation have become apparent. It has been suggested that the problem of integration is embedded in the traditional reductionist method of applied sport science, leading to the eagerness of individual specialists to quantify progress in isolated components. This can lead to “silo” working and decontextualized learning environments that can hinder athlete preparation. To address this challenge, we suggest that ecological dynamics is one theoretical framework that can inform common principles and language to guide the integration of sport science sub-disciplines in a Department of Methodology. The aim of a Department of Methodology would be for group members to work within a unified conceptual framework to (1) coordinate activity through shared principles and language, (2) communicate coherent ideas, and (3) collaboratively design practice landscapes rich in information (i.e., visual, acoustic, proprioceptive and haptic) and guide emergence of multi-dimensional behaviors in athlete performance

    Sport specialization in youth: A literature review

    Get PDF
    Objective: Youth participation in sport is reviewed to include its history, current growth patterns, reasons behind sport specialization, and the implications of sport specialization. The effects of early skill acquisition, and the sociological, psychological, and physical/physiological aspects to help develop safeguards to meet the needs of young athletes are discussed. Study Design and Selection: A review of the research and scholarly literature related to the youth population in the United States was performed. This included accessing the Mayo Clinic Library database, MANTIS, and Index Medicus. Results and Discussion: Specialization in a single sport, although not new to society, has become increasingly popular. Sport specialization training can begin as early as at the age of 5 or 6. The training is throughout the year and may take up to four hours every day. Some in the sports community find sport specialization to be a reflection of a highly developed society and see the skill acquisition and enhancement as beneficial to success in a given sport; the potential for a collegiate athletic scholarship or making a varsity, elite, or even professional level team. Regular physical activity and sport, together with a balanced diet, are essential to promote optimal growth and maturation, sufficient physical fitness and mental vigor, as well as psychological and social benefits that help in coping with stress and anxiety. However, too much or too specific involvement with a sport or activity can be potentially dangerous, involving physiological/physical, psychological, and sociological risks to youth. Despite the importance of this topic, there is a lack of a substantial reference base pertaining specifically to sport specialization. The results were often limited to a non-specific age range within the youth population and primarily of United States youth as opposed to a worldwide population. Also, a majority of the references contained more physiological results as opposed to psychological and sociological findings. The results and conclusions drawn from this sampling cannot be generalized to all sports or athletes as a whole. Conclusion: Sport specialization by youth is a contentious issue that needs to be fully understood by all involved in sport. The potential health, psychological, and sociological risks must be weighed against the benefits of obtaining sharper skills, which may enhance playing time, possibly bringing scholarship opportunities, or reaching to an elite level of play

    Effects of a Motivational Climate on Psychological Needs Satisfaction, Motivation and Commitment in Teen Handball Players

    The aim of this study was to examine the effects of the motivational climate created by the coach and perceived by a group of young high-performance handball players on their sport motivation, self-determination, sport psychological needs and sport commitment. The study participants were 479 young handball players. The age range was 16–17 years old. Players were administered a battery composed of a Perceived Motivational Climate in Sport Questionnaire, Sport Motivation Scale, the Basic Psychological Needs in Exercise Scale and Sport Commitment Questionnaire to measure the above-mentioned theoretical constructs. Results showed that the handball players showed high levels of a task-involving climate, of basic psychological needs satisfaction and of self-determined motivation and commitment. Higher levels of basic psychological needs such as autonomy and competence were associated with a higher task-involving climate, self-determined index and sport commitment (task-involving climate–basic psychological needs (ÎČ = 0.55; 95% IC 0.387/0.682; p = 0.001); Ego-involving climate–basic psychological needs (ÎČ = 0.06; 95% IC −0.069/0.181; p = 0.387); Basic psychological needs–self-determined index (ÎČ = 0.48; 95% IC 0.376/0.571; p = 0.001); Self-determined index–commitment (ÎČ = 0.58; 95% IC 0.488/0.663; p = 0.001). The obtained model showed that basic psychological needs mediated the association between a task-involving climate and self-determination, and self-determination mediated the association between basic psychological needs satisfaction and commitment
